[GitHub] [hive] vihangk1 opened a new pull request #1948: HIVE-24741: get_partitions_ps_with_auth performance improvement
vihangk1 opened a new pull request #1948:
URL: https://github.com/apache/hive/pull/1948
### What changes were proposed in this pull request?
This PR improves the performance of get_partitions_ps_with_auth for certain cases when it is requesting for all the partitions. get_partitions_ps_with_auth is not directSQL enabled and if it is requesting for all the partitions, we can redirect it to a faster partitions API which supports directSQL. When filters are provided the API continues to use existing datanuclues path so there is no change with that behaviour.
### Why are the changes needed?
Performance improvement for a HMS API.
### Does this PR introduce _any_ user-facing change?
No
### How was this patch tested?
Modified existing unit-test to make sure it is working as expected. Also tested on a real-world workload where performance improvement was substantial.
